[2010] EWHC 3136 (Admin)
There could not be duality of detention of a foreign national under immigration detention and a sentence of imprisonment. The power to detain under the UK Borders Act 2007 s.36(1), pending a decision on deportation, would arise when and only when the prisoner had served the period of imprisonment.
